NGK Spark Plugs for 2ZZ-GE
Set of 4 NGK BKR7EIX Iridium Spark Plugs for the 2ZZ-GE. These plugs are one heat range cooler and gapped a few thousandths narrower than stock plugs.
The narrower gap will help to ensure consistent firing in forced induction applications.
The cooler heat range is correct for forced induction and higher performance NA motors.
These are the same plugs that we supply all our forced induction kits.
